The aim of this study was to evaluate if the positive effects recorded on glycemic control with CSII were maintained on the long term compared to multi-daily injections (MDI). The secondary objective was to evaluate if there is a reduction of type and number of cardiovascular events (CV) in CSII group compared to MDI group after 8 years of observation. This retrospective, observational trial evaluated 104 diabetic patients with prior treatment with MDI initiating CSII therapy compared to 109 diabetic patients continuing MDI.
